The DoubleLinePlacer is a special node placer that places its children in two lines. This node placer is especially useful for leaves with great width.

Property Detail
doubleLineSpacingRatioproperty
doubleLineSpacingRatio:Number

Specifies the ratio of the spacing (spacing) between the root and the children in the upper line and the spacing between the two lines of subtrees.

By default, the ratio is 0.33 due to backwards compatibility.


Implementation
    public function get doubleLineSpacingRatio():Number
    public function set doubleLineSpacingRatio(value:Number):void

Constructor Detail
DoubleLinePlacer()Constructor
public function DoubleLinePlacer(init:Boolean = true)

Creates a new DoubleLinePlacer with the default modification matrix.

Parameters
init:Boolean (default = true) — An internally used switch to help handle proper instance initialization in inheritance chains where classes can have multiple constructor-like factory methods. This parameter can safely be ignored/omitted when calling the constructor.

override protected function determineChildConnector(child:Node):int

Returns com.yworks.yfiles.layout.tree.NodePlacerCompanion.DIRECTION_NORTH

Parameters
